Unity > Launcher ... changed behavior after upgrading to 12.04

Hi @all

After upgrading to 12.04 the behavior for double-clicking the launcher-icons has changed.

When I previously (Ubuntu 11.10) double-clicked an icon in the launcher - e.g. the gnome-terminal - and there more then one gnome-terminals open (also on different workspaces) a preview with all gnome-terminals on all workspaces disappeared.

Now (Ubuntu 12.04) this behavior has changed. Here is this preview limited to the current workspace. The gnome-terminal from the other workspaces will be ignored.
